[Ord. 1460 § 7, 2024.]

15.25.080 Prohibition of turbid discharges. Revised 5/24

A. No person shall discharge or cause to be discharged into the public stormwater drainage, surface water systems, or waterways any turbid fluid or liquid, including, but not limited to, stormwater containing any sediment or mercury-contaminated discharges that can cause or contribute to a violation of DEQ and/or other applicable water quality standards. The commencement, conduct, or continuance of turbid or mercury-contaminated discharges to the public stormwater drainage, surface water systems, or waterways is prohibited except as set forth in this section.

B. The prohibition set forth in subsection (A) of this section shall not apply to any nonstormwater discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered by the Oregon Department of Environmental Quality under the authority of the federal Environmental Protection Agency; provided, that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations; and provided, that Marion County has granted written approval for any discharge to the public stormwater drainage, surface water systems, or waterways. [Ord. 1460 § 8, 2024.]

15.25.090 Mercury waste disposal prohibitions. Revised 5/24

No person shall throw, deposit, leave, maintain, keep, or permit to be thrown, deposited, left, or maintained, in or upon any public or private property, driveway, parking area, street, alley, sidewalk, component of the public stormwater drainage, surface water systems, or waterways, any mercury or mercury-contaminated refuse, rubbish, garbage, litter, or other discarded or abandoned objects, articles, and accumulations, so that the same may cause or contribute to pollution. Mercury wastes deposited in proper waste receptacles for the purposes of collection are exempt from this prohibition. [Ord. 1460 § 9, 2024.]

15.25.100 Discharges in violation of industrial or construction activity NPDES stormwater discharge permit. Revised 5/24

Any person subject to an industrial or construction activity NPDES stormwater discharge permit shall comply with all provisions of the permit. Failure to comply with all provisions shall constitute a violation of this chapter. Proof of compliance with the permit may be required in a form acceptable to the director prior to or as a condition of a subdivision map, site plan, building permit, or development or improvement plan; upon inspection of the facility; during any enforcement proceeding or action; or for any other reasonable cause. [Ord. 1460 § 10, 2024.]

15.25.110 Waterway protection. Revised 5/24

Every person responsible for property through which a waterway passes shall maintain and stabilize that portion of the waterway that is within the responsible person’s property lines to protect against erosion and degradation of the waterway originating from the property which creates turbidity or results in a mercury-contaminated discharge. “Maintain” and “stabilize” as used in this section mean keeping that portion of the waterway that is within the property lines free of trash, debris, excessive vegetation, and other obstacles that would pollute, contaminate, or retard the flow of water through the waterway in a way that creates turbidity or a mercury-contaminated discharge. “Maintain” also includes the maintenance of existing privately owned structures within or adjacent to a waterway, so that the structures will not create turbidity or a mercury-contaminated discharge. “Erosion” as used in this section includes the removal of bank vegetation that will result in bare slopes subject to erosion which result in turbidity or a mercury-contaminated discharge. This chapter shall not be interpreted to restrict a person responsible for property from enhancing or establishing the planting of riparian buffers or to perform maintenance within those areas. [Ord. 1460 § 11, 2024.]

15.25.120 Natural occurrence of erosion. Revised 5/24

Erosion, or the release of mercury-contaminated wastes or discharges, where it occurs naturally, such as the result of fire-caused damage or other natural reasons, is excluded from the provisions of this chapter. [Ord. 1460 § 12, 2024.]

15.25.130 Requirement to monitor and analyze. Revised 5/24

The director may require by written notice to the property owner that any person engaged in any activity and/or owning or operating any facility which may cause or contribute to turbid runoff or mercury-contaminated discharges to the public stormwater drainage, surface water systems, or waterways undertake at the owner’s expense any monitoring and analyses and furnish any reports to the director as deemed necessary to determine compliance with this chapter. [Ord. 1460 § 13, 2024.]

15.25.140 Illicit discharge procedure. Revised 5/24

Notwithstanding any other requirements of law, as soon as any person responsible for a facility or operation, or responsible for emergency response for a facility or operation, has information of any known or suspected release of materials which are resulting or may result in turbid runoff or mercury-contaminated discharges into the public stormwater drainage, surface water systems, or waterways from the facility, the person shall take all necessary steps to ensure the discovery, containment, and cleanup of the release. Upon discovery of any turbid runoff or mercury-contaminated discharges, the responsible person shall immediately notify the director. [Ord. 1460 § 14, 2024.]

15.25.150 Authority to inspect. Revised 5/24

When the director determines it is necessary to inspect to enforce any provision of this chapter, the director may enter those premises to inspect them and to inspect and copy records related to stormwater compliance. The director shall provide a written request to enter and inspect the premises by delivering the request to a responsible person or by posting the request at a conspicuous location on the premises. If a responsible person refuses entry or fails to respond to the request, the director may seek a warrant or other assistance from any court of competent jurisdiction in obtaining entry. [Ord. 1460 § 15, 2024.]

15.25.160 Authority to conduct sampling and/or testing. Revised 5/24

During any inspection pursuant to this chapter, the director may take any samples and perform any testing deemed necessary to aid in the pursuit of the inquiry or to record site activities. [Ord. 1460 § 16, 2024.]

15.25.170 Requirement to eliminate turbid runoff or mercury-contaminated discharges. Revised 5/24

Failure to comply with the requirements of the notice within the time stated shall constitute a violation of this chapter. [Ord. 1460 § 17, 2024.]

15.25.180 Requirement to remediate. Revised 5/24

Whenever the director finds that turbid or mercury-contaminated discharges are taking place, or have occurred, that will result in or has resulted in pollution of stormwater to the public stormwater drainage, surface water systems, or waterways, the director may require by written notice to the property owner that the pollution be remediated, and the affected property restored within a specified time.
